Adobe ID and document cloud expiration with no paid subscriptions - terms of service doesn't provide any answers....

Hi,

Really not great I think: Adobe really leaves us users in the dark what period they use to determine when to flag an account/Adobe ID as inactive: in the terms of service at "10. Termination" it says: 10.2 Termination by Us. Unless stated in Additional Terms, we may at any time terminate these terms (and your access to Services or Software) with you if: (e) there has been an extended period of inactivity in your free account" .... wonderful but what does Adobe see as "extended"????

This is really not great, how will I know how long I can have my documents uploaded in Document Cloud with it not being removed if I don't regularly login?
